Question

Express in scientific notation. Make sure your answer has the same number of significant figures as the starting value.

61,103 = _____
​

Answer 1

61,103=6.1x10^4 (simplified version is 6.1E4)

Explanation:

61,103, when rounded, becomes 61,000. Upon rounding it, you are able to follow the rules of significant figures and move the decimal up until it becomes 6.1000 and after doing so, count how many zeroes you have, drop the zeroes, and multiply it by ten to the power of however many zeroes there were. (fun fact, the tiny capital E on the calculators is a substitute for the ten to the power method that is significantly quicker to both type and write)
